BACKGROUND - Surgical site infections (SSI) are one of the most common complications after hepato-pancreato-biliary surgery. Infectious complications may lead to an associated immune-modulatory effect that inhibits the body's response to cancer surveillance. We sought to define the impact of SSI on long-term prognosis of patients undergoing surgical resection of extrahepatic biliary malignancies (EHBM).
METHODS - Patients undergoing surgery for EHBM between 2000 and 2014 were identified using a large, multi-center, national cohort dataset. Recurrence free survival (RFS) was calculated and a multivariable Cox proportional hazards model was utilized to identify potential risk factors for RFS including SSI.
RESULTS - Seven hundred twenty-eight patients included in the analytic cohort; 236 (32.4%) patients had perihilar cholangiocarcinoma, 241 (33.1%) gallbladder cancer, and 251 (34.5%) distal cholangiocarcinoma. A major resection, liver resection, was performed in 205 (28.3%) patients, while 110 (15.2%) patients had a pancreaticoduodenectomy. The overall incidence of morbidity was 55.8%; among the 397 patients who experienced a complication, 161 patients specifically had an SSI. The SSI occurred as an infection of the surgical site (n = 70, 9.6%) or formation of an abscess in the operative bed (n = 91, 12.5%). SSI was associated with long-term survival as patients who experienced an SSI had a median RFS of 19.5 months compared with 30.5 months for those patients who did not have an SSI (HR 1.40, 95% CI 1.08-1.80; p = 0.01). Among 279 patients who had EHBM that had no associated lymph node metastases, well-to-moderate tumor differentiation, as well as an R0 resection margin, SSI remained associated with worse RFS (HR 1.84, 95% CI 1.03-3.29; p = 0.038), as well as overall survival (HR 1.87, 95% CI 1.18-2.97; p = 0.008).
CONCLUSION - SSI was a relatively common occurrence following surgery for EHBM as 1 in 10 patients experienced an SSI. In addition to standard tumor-specific factors, the occurrence of postoperative SSI was adversely associated with long-term survival.

BACKGROUND - The objective of this study is to evaluate use of the American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) online risk calculator for estimating common outcomes after operations for gallbladder cancer and extrahepatic cholangiocarcinoma.
METHODS - Subjects from the United States Extrahepatic Biliary Malignancy Consortium (USE-BMC) who underwent operation between January 1, 2000 and December 31, 2014 at 10 academic medical centers were included in this study. Calculator estimates of risk were compared to actual outcomes.
RESULTS - The majority of patients underwent partial or major hepatectomy, Whipple procedures or extrahepatic bile duct resection. For the entire cohort, c-statistics for surgical site infection (0.635), reoperation (0.680) and readmission (0.565) were less than 0.7. The c-statistic for death was 0.740. For all outcomes the actual proportion of patients experiencing an event was much higher than the median predicted risk of that event. Similarly, the group of patients who experienced an outcome did have higher median predicted risk than those who did not.
CONCLUSIONS - The ACS NSQIP risk calculator is easy to use but requires further modifications to more accurately estimate outcomes for some patient populations and operations for which validation studies show suboptimal performance.

Endoscopic retrograde cholangiopancreatography with single-balloon enteroscopy is feasible in patients with a prior Roux-en-Y anastomosis.
Dellon ES, Kohn GP, Morgan DR, Grimm IS
(2009) Dig Dis Sci 54: 1798-803
MeSH Terms: Adult, Anastomosis, Roux-en-Y, Bile Ducts, Bile Ducts, Intrahepatic, Biliary Tract Surgical Procedures, Cholangiopancreatography, Endoscopic Retrograde, Cholangitis, Sclerosing, Feasibility Studies, Female, Gastric Bypass, Humans, Liver, Liver Transplantation, Male, Middle Aged
Show Abstract · Added May 18, 2016
The purpose of this study is to describe the feasibility of using single-balloon enteroscopy (SBE) to perform endoscopic retrograde cholangiopancreatography (ERCP) in patients who had a prior Roux-en-Y (RY) anastomosis. This case series describes four patients, one with RY gastric bypass, two with RY due to bile duct injury, and one with RY after liver transplantation, who underwent ERCP with SBE. Cholangiography was successful in three of the four patients. In the procedure that was not successful, the enteroenterostomy site could not be located. The successful procedures ranged from 65-91 min in duration. Medication doses were higher than with typical ERCPs. No procedural complications occurred. SBE for ERCP is a feasible option for endoscopic access to the biliary tree in patients with prior RY anastomoses. Limitations of this technique include the time requirement, delay in identification of the enteroenterostomy site, potential learning curve, and immature technology lacking accessories.

Show Abstract · Added December 26, 2013
A 10-month-old, previously healthy boy presented with one week of mild jaundice, light-colored stools and irritability. Abdominal sonography showed a large type I choledochal cyst and a separate, distinct cystic mass at the head of the pancreas. Magnetic resonance cholangiopancreatography was performed to evaluate the relationship of the two lesions. A type I choledochal cyst was confirmed, and a coexisting type III choledochocele was identified as the second cystic structure in conjunction with pancreaticobiliary malunion. The infant had complete resection of the type I choledochal cyst with Roux-en-Y hepaticojejunostomy, and anterior duodenotomy with marsupialization of the choledochocele. After five years of follow-up, the child is thriving and has had no recurrence of his symptoms. An exhaustive review of the literature identifies only one previous case of synchronous types I and III choledochal cysts, and this association is not clearly defined among the traditional classifications of type IV multiple choledochal cysts. Because operative management of a type III cyst requires the addition of a transduodenal approach, we encourage accurate reporting of mixed type choledochal cysts for the benefit of surgical planning, epidemiologic tracking and outcomes.

Show Abstract · Added February 11, 2015
The results of duct-to-duct biliary reconstruction in six pediatric patients who received a living donor liver transplant aged from 2 months to 11 yr old are reported. The graft was either entire or a part of the left lateral segments. The orifice of the bile duct of the graft was anastomosed to the recipients' hepatic duct in an end-to-end fashion by interrupted suture using 6-0 absorbable material. A transanastomotic external stent tube (4 Fr) was passed through the stump of the recipients' cystic duct. Mean time for reconstruction was 24 min. All the recipients survived the operation and reinitiated oral intake on postoperative day 3. There were no early biliary complications. One 5-yr-old boy suffered from an anastomotic stenosis 9 months after transplantation. He underwent re-anastomosis by Roux-en Y (R-Y) procedure and recovered uneventfully. Duct-to-duct anastomosis in pediatric living donor liver transplantation has benefits while the complication rate is comparable to R-Y reconstruction.

Show Abstract · Added March 5, 2014
Bile leaks occur in up to 27 per cent of liver transplant patients after biliary reconstruction. Synthetic sealants have not been investigated for these biliary procedures. We performed a randomized controlled study to evaluate a novel absorbable polyethylene glycol/collagen biopolymer sealant (CT3 Surgical Sealant) after incomplete end-to-end choledochocholedochostomy (CDCD) in pigs. Pigs (n = 18) underwent transection of the common bile duct and incomplete CDCD over a T-tube, leaving a one-sixth circumferential defect anteriorly. Animals were randomly assigned to treatment (CDCD with sealant, n = 9) or control (no sealant, n = 9). Drains were used to monitor leak volume and bilirubin (bili) concentration. Cholangiography was performed on postoperative day 3. Leaks were defined as drain bili/serum bill > 3, total drain output > 10 mL/kg, and/or extravasation on cholangiography. Animals sacrificed at 3 and 8 weeks (n = 4 and n = 5 from each group, respectively) underwent pathologic examination of the CDCD site. Statistical methods included Student's t test, chi2, linear regression, and analysis of variance procedures. The control group had a higher drain output rate over the first 4 postoperative days than the treatment group (P < 0.05, analysis of variance). Five of nine (56%) control and one of nine (11%) treatment animals had a bile leak (P < 0.05, chi2). There was no major inflammatory response to the sealant versus controls. We conclude that CT3 is effective in decreasing biliary leaks in an incomplete CDCD porcine model with no major adverse pathologic changes. This sealant should be considered for trials for biliary reconstruction in humans.
